My baby is 3 weeks old and when put to bed, lies awake for a long time just looking around. She doesn't usually cry, apart from the odd whinge now and then, but it seems to take a long time for her to fall asleep, sometimes more than an hour. When she wakes she is very unsettled and really screaming for food. We try not to pick her up when she becomes unsettled and have hardly ever 'rocked' her to sleep (maybe once her twice in the first couple of days once home). She is bottle fed and her feeds are quite varied, anything from 50ml to 140ml! Any suggestions would be greatly appreciated.
